Osiris addresses

Three published addresses for the same market. Copy rather than retype.

This list is published, not monitored. An address that opens is not an address that is genuine, and the check that settles it belongs to the every time list.

How often
Every session, before anything else.
How long
Ten seconds if you set up storage properly during the one time tasks.
What it prevents
Arriving at a retired address, a near miss, or something somebody handed you.
If you skip it
You are working from memory, a bookmark or a message, all of which rot without telling you.
How you notice you stopped
You start typing the beginning of an address and letting autocomplete finish it.

Where it should come from

A file you control, with the date beside each entry. Not memory, because nobody recalls fifty six characters and near enough is precisely the failure being exploited. Not a browser bookmark, because it hides the string behind a name you chose and removes the moment you would have noticed a change.

A link somebody sent you

Treat where it came from as carrying no information at all. A link from a forum you have read for years, a person you trust, or a site that has been right before is exactly as unverified as one from a stranger.

Not because those sources are dishonest. Because none of them can prove anything about an address, and the thing that can takes under a minute at the other end.

The timing that mattersAn address that first reaches you during an outage deserves more suspicion than one that reaches you on an ordinary day, not less. That window is worked deliberately, because the usual comparison is unavailable.

Copy, never retype

Every manual transcription is a chance to introduce an error that will look exactly like an attack when it fails, and it costs you the certainty that would have made the next task unnecessary. Copying also means the string that reaches the address bar is the string you chose, which matters for the check on the next page.
